Flutter is a powerful UI toolkit developed by Google to build natively compiled applications for mobile, web, and desktop — all from a single codebase. In this guide, we’ll walk you through creating your first Flutter app from scratch, perfect for beginners!
📱 What is Flutter?
Flutter is an open-source SDK that allows developers to create cross-platform apps using a single programming language – Dart. With Flutter, you can create apps that look and feel native on both Android and iOS, without writing separate codebases.
✅ Why Choose Flutter for App Development?
- Cross-platform development
- Hot reload for faster coding iterations
- Rich widget library for modern, responsive UIs
- Strong community and support from Google
🧰 Prerequisites to Build a Flutter App
Before starting, make sure you have the following installed:
- Flutter SDK
- Dart SDK (comes with Flutter)
- Android Studio or Visual Studio Code
- Emulator or physical device for testing
🔧 Step-by-Step Guide to Create a Flutter App
Step 1: Install Flutter SDK
Visit the Flutter installation page and follow the instructions for your operating system. After installing, run the following command to check for dependencies:
|
1 |
flutter doctor |
Step 2: Create a New Flutter Project
Open your terminal or command prompt and run:
|
1 2 |
flutter create my_first_app cd my_first_app |
Step 3: Open the Project in Your IDE
Launch Android Studio or VS Code and open the newly created folder my_first_app. Explore the lib folder and pubspec.yaml file.
Step 4: Run Your App
Connect an emulator or a physical device and use this command:
|
1 |
flutter run |
This will launch the default demo Flutter app.
Step 5: Modify the Main Dart File
Open lib/main.dart and replace the content inside the home: widget to build your custom UI:
|
1 2 3 4 5 6 7 8 |
home: Scaffold( appBar: AppBar( title: Text('My First Flutter App'), ), body: Center( child: Text('Hello, Flutter!'), ), ), |
📦 Adding Packages in Flutter
Edit your pubspec.yaml file to include packages like google_fonts or http.
|
1 2 3 4 |
dependencies: flutter: sdk: flutter google_fonts: ^6.1.0 |
Then run:
|
1 |
flutter pub get |
🧪 Testing and Debugging
Use Flutter’s built-in test tools:
- Unit testing
- Widget testing
- Integration testing
Run tests using:
|
1 |
flutter test |
📤 Build and Release
When your app is ready, build it for release:
For Android:
|
1 |
flutter build apk |
For iOS:
|
1 |
flutter build ios |
Follow platform-specific publishing instructions to deploy your app on the Play Store or App Store.
